FILTER-HOLDER
Never remove the filter-holder during operation of the group. The shutdown is controllable with coffee
spouts: they no longer eject liquid.
Be careful to always keep the filter-holder engaged in the group, emptied of coffee cake, to keep them
warm.
In case of an extended stopping period, remove the filter-holder from the group, taking care to eject the
used grounds remain in the filter-holder.
Tighten the filter-holder until to be in contact with the seal, exceeding a little bit. The sealing is guaranteed.
Do not unnecessarily try to crush the seal by tightening the filter at the maximum of your possibilities. It may
damage the seal prematurely.
To empty the coffee filters used, turn the filter holder upside-down and lightly tap it on the edge of a
wooden box. Never strike it against metal or other hard objects.
DIGITAL MANOMETER M1 : BOILER PRESSURE
The boiler pressure is adjusted in factory between 0,08 MPa (12 PSI) and 0,1 MPa (15 PSI). This value varies
slightly around its nominal temperature, due to the PID system which controls the heating and limits the
current consumption to its minimum.
Factory settings: 1, 2 MPa with setting range from 0,08 MPa to 0,14 MPa.
NOTE: An over-heating thermostat cut the power on the general relay, in case of an abnormal high
temperature. The machine is not anymore supplied.
DIGITAL MANOMETER M2: PUMP PRESSURE
The pump pressure is adjusted at 0,9 MPa in the factory. Value which allows the best extraction of coffee
flavors. A bypass system evacuates over-pressure.
NOTE: Simultaneous operation of all the groups can impact a little bit the pressure level.
Visualization of the presence of water network is done by consulting the gauge

How to use the programmed doses
Simply select one of the buttons available on each keypad to obtain the doses or the programmed
drinks.
The selected dose is shown by a blinking led on the keypad.
The flow can be stopped by repressing:
o
The same button or
o
The STOP button (which is also the programming and continuous flow button).
